Nowhere in the Practical Test Standards are you required to demonstrate such a risky maneuver. Just think if you flew ATTI mode and got close to a building or other structure that close and had an updraft from underneath, would you be able to prevent being pushed up into the building, my guess is an absolute NO. This maneuver looks cool because of the outcome, but should it have ended differently I guess we would be saying how stupid of the pilot to put everyone at risk. If a car came speeding behind you and changed lanes coming inches from your car, and family inside, and the other car, on the other lane would you say what an awesome driver, or would you be cussing him out.
